Depo-Provera is a prescription and the injection is obtained from your healthcare provider every 11 to 13 weeks. The healthcare provider will inject the synthetic hormone in the upper arm or in the buttocks. The initial injection is given within the first five days of your menstrual bleeding.
A reason your knees may be getting sore from deadlifts is because your form is not quite right. If your knees drift too far forward when deadlifting, this turns the exercise into more of a knee-dominant one, notes strength coach Mike Robertson.
Your hamstrings are responsible for knee flexion and work with the gluteal muscles to extend the hip. When your hamstring muscles and tendons are tight, they affect both the knee and hip joints. But as part of the posterior chain, tight hamstrings can also affect the spine. Deadlifts are intended to work the hamstrings, but poor execution forces you to use your back muscles instead.
